[Qemu-devel] [PATCH v2 0/3] Update AppleSMC for OS X Sierra 10.12.4 guests

[Gabriel L. Somlo]

As of 10.12.4 (currently the latest Sierra update), OS X refuses to boot
unless the AppleSMC supports a third I/O port, which provides the current
error status when read.

New since v1:

        - 1/3: don't touch the default OSK string, as it's unnecessary
                at this time

        - 2/3: don't consolidate I/O regions, leave as-is for data
                and cmd; This patch now implements the error-code state
                machine, AND adds an i/o region dedicaded to the error
                status port, complete with read/write access methods.

        - 3/3: optional patch setting access width to 1-byte on data and
                cmd i/o regions. Tested on OS X versions 10.[6..12].

> This series consists of three patches:
>
>       - 1/3: indentation/whitespace cleanup for applesmc.c to the point
>               where it now passes scripts/checkpatc.pl, and allows
>               subsequent changes to look nice in diff-patch format :)
>
>       - 2/3: consolidate Port I/O into a single region, and invoke
>               appropriate read/write methods based on the offset being
>               accessed
>
>       - 3/3: implement read-only error/status port, and update
>               data and command read/write methods to correctly
>               maintain the state machine for keeping the status_1e
>               value up to date.
